1U 350W PSU for FSP systems

This KHACHIMO power supply is built for 1U chassis that require an ATX-compatible unit with a 350W continuous rating and a 400W peak capacity. It suits administrators and integrators who need reliable power in rack-mount or compact enclosures.

Replaces legacy FSP350-601U units

It serves as a direct replacement for the FSP350-601U model, adding 80 PLUS Gold efficiency and a Zero RPM fan mode that eliminates noise at low and medium loads. The upgrade is worth it when quieter operation and lower idle consumption matter for the deployment.

Verify 1U fit and ATX pinout

Confirm the chassis accepts a 1U form-factor ATX supply and that the motherboard uses the standard main and CPU power connectors provided. Ensure the system does not draw more than the rated 350W continuous load.

Questions about this item

What form factor does this 350W ATX power supply use for mounting in a 1U chassis?

It uses a standard 1U ATX form factor designed to fit 1U rackmount or slimline cases that accept this height.

How is the unit installed and which connection step is often missed?

Slide the unit into the 1U bay, secure it with the chassis screws, then attach the 24-pin ATX, CPU and peripheral cables; the step often missed is fully seating the 24-pin connector until the latch clicks.

What maintenance will this 80 PLUS Gold PSU need over its service life?

Clean dust from the intake and exhaust vents periodically; the Zero RPM fan mode reduces wear, but the fan should still be checked for smooth rotation during high-load operation.
